I've got Microsoft Security Essentials and the full scan takes three and a half hours. A MS tech once told me to download Malwarebytes scanner but to make sure to just run the scan and then dis-install the Malwarebytes. Does anybody know if the Malwarebytes scans faster? And I would need the "on-demand" version, right? And could I download that onto a flash drive and would that be sufficient so I wouldn't have to be dis-installing it every time I run a scan? And (last question I promise) if I get the on-demand one for a pen drive, do I want the "portable" version? And (okay, it was the second to last question) does anybody have a link for the exact Malwarebtes one that would fit my needs? Phew! Thanks!
